When people are way too smug about their wrong answer.
Posting guidelines.
All posts in this community have come from elsewhere, it is not original content, the poster in this community is not OP. The person who posts in this community isn’t necessarily endorsing whatever the post is talking about and they are not looking to argue with you about the content in the post.
You are welcome to discuss and debate any topic but arguments are not welcome here. I consider debate/discussions to be civil; people with different opinions participating in respectful conversations. It becomes an argument as soon as someone becomes aggressive, nasty, insulting or just plain unpleasant. Report argumentative comments, then ignore them.
There is currently no rule about how recent a post needs to be because the community is about the comeback part, not the topic.
Rules:
• Be civil and remember the human.
• No trolling, insults or name calling. Swearing in general is fine, but not to insult someone.
• No bigotry of any kind, including homophobia, transphobia, sexism and racism.
• You are welcome to discuss and debate any topic but arguments are not welcome here. I consider debate/discussions to be civil; people with different opinions participating in respectful conversations. It becomes an argument as soon as someone becomes aggressive, nasty, insulting or just plain unpleasant. Report argumentative comments, then ignore them.
• Try not to get too political. A lot of these posts will involve politics, but this isn’t the place for political arguments.
• Participate in good faith - don’t be aggressive and don’t argue for arguements sake.
• Mark NSFW posts if they contain nudity.
• Satire is allowed but please start the post title with [satire] so other users can filter it out if they’d like.
Please report comments that break site or community rules to the mods. If you break the rules you’ll receive one warning before being banned from this community.
This community follows the rules of the lemmy.world instance and the lemmy.org code of conduct. I’ve summarised them here:
- Be civil, remember the human.
- No insulting or harassing other members. That includes name calling.
- Respect differences of opinion. Civil discussion/debate is fine, arguing is not. Criticise ideas, not people.
- Keep unrequested/unstructured critique to a minimum.
- Remember we have all chosen to be here voluntarily. Respect the spent time and effort people have spent creating posts in order to share something they find amusing with you.
- Swearing in general is fine, swearing to insult another commenter isn’t.
- No racism, sexism, homophobia, transphobia, xenophobia or any other type of bigotry.
- No incitement of violence or promotion of violent ideologies.

Yep! You're totally correct. They're indeed highly specialized, it's a chain that starts with a proerythroblast that would look more like a "normal" cell going all the way to the erythrocyte, the familiar red blood cell.
Very frequently in biology we create definitions and groupings that get more and more specific, but without taking away from the original group: for instance, carnivores are a specific group of animals with specialized characteristics... But they're still mammals. And mammals are still animals. And animals are still Eukaryotes. And so on.
Cells do not follow the same type of definitions that we would use for groupings, but the logic still applies - losing a nucleus won't make this cell suddenly not a cell. In fact, the membrane is still highly dynamic, there are still internal and external communication mechanisms, and there's a metabolism - glycolysis.
If you’re not already a teacher/lecturer you’d make a great one!
